Multi-Gigabit Wireline Systems over Copper: An Interference Cancellation Perspective
Interference cancellation is the main driving technology in enhancing the
transmission rates over telephone lines above 100 Mbps. Still, crosstalk
interference in multi-pair digital subscriber line (DSL) systems at higher
frequencies has not been dealt with sufficiently. The upcoming G.(mg) fast DSL
system envisions the use of extremely high bandwidth and full-duplex
transmissions generating significantly higher crosstalk and self-interference
signals. More powerful interference cancellation techniques are required to
enable multi-gigabit per second data rate transmission over copper lines. In
this article, we analyze the performance of interference cancellation
techniques, with a focus on novel research approaches and design considerations
for efficient interference mitigation for multi-gigabit transmission over
standard copper lines. We also detail novel approaches for interference
cancellation in the upcoming technologies.Comment: 7 pages, 5 figures, 1 Tabl
